Writing
Authorship, A Work
noun, verbal noun
An author makes writing in an activity known as authorship.
Note that this word isn't a general term for writing! 著作 has a more specific nuance — it's mostly used to talk about a work or the writings of a particular author. You'll also see it often in the compound 著作権, in relation to copyright.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own.
彼女は少なくとも五十は著作があります。
She has no less than fifty books published.
